LEVELER FOR CHARGES OF COKE-OVENS.

To all whom it may concern:

Be it known that I, DANIEL F. LnrLnY, a citizen of the United States,residing at Connellsville, in the county of Fayette and State ofPennsylvania, have invented a new and useful Leveler for Charges ofC0ke-Ovens, of which the following is a specification.

This invention has reference to improvements in means for leveling afuel charge in an oven, preparatory to firing the same, and theinvention aims to produce a device which may be adapted readily todifferent ovens, regardless of variations in the height of the same, thedevice being adapted to bring the pile of material within the oven to asubstantially level surface by the movement of the leveling apparatusinto and out of the oven.

The invention will be understood best from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings.

In the drawings :-F igure 1 is a side elevation of the coke leveler;Fig. 2 is a plan view of the same; Fig. 3 is a front elevation, theleveling head being omitted; Fig. 4 is a detail elevation (on a largerscale than the other figures) of the means for elevating and loweringthe leveler-carrying-portion of the structure; Fig. 5 is an elevation ofthe structure of Fig. 4 as seen from a point at right angles to the viewpoint of Fig. 4, certain parts being in section to show the bearings;Fig. 6 is a structural diagram showing the means for operating theleveler; Figs. 7 8 and 9 are diagrammatic views showing the arrangementof the cables which actuate the plunger or ram; and Fig. 10 is a topplan, diagrammatic in nature, the view depicting the means whereby avertical adjustment and a tilting of the ram are effected.

Coke ovens of the type to which this invention is particularly adapted,are built in long rows with a yard extended to one or both ends of therow, and along the face of the ovens in the yard, there is laid a track.

In the drawings, the ovens are indicated at 1 and the track is indicatedat 2. Adapted to traverse the track 2 is a truck 3 which need not beparticularly described, since the truck 3, as shown in Figs. 1, 2 and 3,is an Specification of Letters Patent.

electric motor 4, on the armature shaft of which is a gear pinion 5meshing into a gear wheel 6 secured to a shaft 7 which is suitablysupported for rotation on the truck 3. Journaled on the shaft 7 as shownin Figs. 4 and 5 is a sprocket wheel 11, connected by means of asprocket chain 14 with a sprocket wheel 13 which is secured to one ofthe axles 12 of the truck 3. Mounted on the shaft 7 is a clutch 9whereby the sprocket wheel 11 may be coupled with the shaft 7. Thus,when the motor 4 is in operation, the truck 3 may be moved to and froalong the track 2 through the medium of a gear train comprising thepinion 5, the gear wheel 6, the shaft 7, the clutch 9, the sprocketwheel 11, the sprocket chain 14, the sprocket wheel 13 and the axle 12-of the truck.

Referring particularly to Figs. 5 and 10 it will be observed that a pairof sprocket wheels 10 and 10 are journaled 011 the shaft 7, and. eitherone of the sprocket wheels 10 and 10 may be coupled up with the shaft 7through the medium of a clutch 8. Another pair of sprocket wheels 10 and10 are journaled on the shaft 7, and these sprocket wheels respectively,may be coupled up with the shaft 7 through the medium of a clutch 8Supported by the side portions of the frame of the truck 3 are shafts 22and 22, reference being had particularly to Figs. 4, 5 and 10. Journaled on one end of the shaft 22 is a sleeve 102 carrying a sprocketwheel 24, connected by means of a sprocket chain 25 with the sprocketwheel 10 on theshaft 7. The sleeve 102 is provided at its outer end witha beveled gear 21. J ournaled 011 the shaft 22 at the same side of themachine as the sleeve 102, is a sleeve 105 provided with a sprocketwheel 24 connected by means of a sprocket chain 25 with the sprocketwheel 10 of the shaft 7. Secured to the outer end of the sleeve 105 is abeveled gear 21*. At the opposite side of the machine, a sleeve 101 isjournaled on the shaft 22, the sleeve 101 being provided with a sprocketwheel 24 about which is trained a sprocket chain 25, the sprocket chain25 being connected with the sprocket wheel 10 upon the shaft 7. Thesleeve 101 carries at its outer end a beveled gear 21. Journaled uponthe shaft 22 at the same side of the machine as the sleeve 101 is asleeve 103 to which is secured a sprocket wheel 24 connected by means of'to the shaft 7 from the motor 4, motion a sprocket chain 25 with thesprocket wheel 10 on the shaft 7. At its outer end, the sleeve 103carries a beveled pinion 21 Referring to Fig. 5 and comparing the samewith Fig. 4, it will be observed that the frame of the truck 3 isprovided upon opposite sides with bearings 15, receiving vertical rods16, terminated at their upper ends in eyes 18, the lower parts of therods 16 being threaded as indicated at 17, to engage with beveled gearwheels 19 and 19. There is a pair of rods 16 at each side of themachine. One rod 16 is threaded into the beveled gear wheel 19 and theother rod is threaded into the beveled gear wheel 19. Upward movement ofthe gear wheels 19 and 19 is prevented by the bearing 15, and downwardmovement of the gear wheels is prevented by a plate 20, constituting apart of the frame of the truck. The beveled gear wheels 19 and 19 ateach side of the truck are connected operatively by means of unitedbeveled gears 23, suitably supported for rotation along the sides of theframe of the truck.

Suppose that the sprocket wheel 10 is coupled to the shaft 7 by means ofthe clutch 8, the sprocket wheel 10 being coupled to the shaft 7 bymeans of the clutch 8. When rotatory movement is imparted will betransmitted from the sprocket wheel 10 to the sprocket chain 25*, andthence into the sleeve 102 by way of the sprocket wheel 24. The beveledpinion 21 at one side of the machine will actuate the beveled pinion 19and the beveled pinion through the medium of the connected beveledpinions 23 will actuate the beveled gear wheel 19 upon the same side ofthe machine. In this manner, the rods 16 at one side of the machine willbe lifted simultaneously, presupposing the shaft 7 is rotated in theproper direction.

From the sprocket wheel 10? motion will be transmitted through thesprocket chain 25 to the sprocket wheel 24, and thence into the sleeve101, the sleeve 101 through the medium of the other beveled gear 21, thebeveled gear 19, the beveled pinions 23 and the corresponding beveledgear 19* effecting an elevation of the rods 16 at the side of themachine in question. Suppose, however, that through the medium of theclutch 8, the sprocket wheel 10 has been coupled to .the shaft 7 andsuppose that through the medium of the clutch 8 the sprocket wheel 10has been coupled up to the shaft 7. Then, motion will be transmittedfrom the sprocket wheel 10 to the chain 25, through the sprocket wheel 21 to the sprocket sleeve 105 and to the beveled gear 21 and attendantparts, the rods 16' being lowered, presupposing that the shaft 7 hasbeen rotated as above described. From, the sprocket wheel 10, motionwill be transmitted through the sprocket chain 25 to the sprocket wheel2%, and thence by way of the sleeve 103 to the other beveled pinion 21"and attendant parts. Thus the rods 16 upon corresponding sides of themachine will be lowered.

By the operation above described, all of the rods 16 have been raisedand lowered with their upper, eye carrying portions 18 in a singlehorizontal plane. It is obvious, however, that the sprocket wheels 10and 10 may be coupled simultaneously to the shaft 7. Likewise, thesprocket wheel 10 and the sprocket wheel 10 may be coupledsimultaneously to the shaft 7, thus effecting independent movementbetween the pairs of rods 16 at opposite sides of the machine, so thatthe eye carrying portions 18 of the rods 16 may be disposed at differentelevations. Likewise, by the proper manipulation of the clutch 8, thesprocket wheels 10 and 10 may be coupled individually to the shaft 7 toeffect a proper vertical adjustment of the pairs of rods 16 at therespective sides of the machine.

When the clutch 8 is disengaged from the pinions 10 and 10 and when theclutch 8" is disengaged from the sprocket wheels 10" and 10, the shaft 7may be driven from the motor -11 to impart movement to the axle 12, inthe manner hereinbefore set forth.

Erected on the truck 3 are upright spaced guides 26 adapted to directthe movement of a frame F made up of side plates 27. Secured to the sideplates 27 of the frame F are blocks 28, receiving pins or bars 29. Thebars 29 pass through the eyes 18 of the rods 16 at opposite sides of theframe, and from what has been said hereinbefore it will be obvious thata vertical movement imparted to the rods 16 will effect a verticaladjustment of the frame F.

Noting particularly Figs. 1 and 2 it will be seen that an electric motor30 is mounted on top of the frame F. The motor 30 is geared as indicatedat 30 to a shaft 31 which is supported for rotation on top of the frameF. Secured to the shaft 31 is a beveled gear 32 meshing with twoopposite beveled gears 33-34 fixed respectively, to shafts 35 and 36.Fixed to the outer ends of the shafts 35 and 36 are gear wheels 37 whichmesh with gear wheels 38. The gear wheels 38 are journaled for rotationon a shaft 40 which is journaled on the frame F, clutches 39 beingprovided, for the purpose of coupling up the gear wheels 38 with theshaft 40. A drum s11 is secured to the shaft 40, and secured to theshaft 40 upon opposite sides of the drum 4A are outer drums 412. Byreason of the gear connection between the motor 30 and the gear wheels38, these wheels rotate in opposite directions. By manipulating theclutches 39 of the shaft 40, the shaft, therefore, may be driven in themotors and the clutches, but since such means may be of any desiredform, a specific description thereof need not be entered into in thisspecification.

Traversing the casing F at the front and at other appropriate points arespaced pairs of rollers 4% receiving between them a rectangular tubularmember simply indicated in Fig. 6 but which may be made in anyappropriate manner for the purposes of the present invention. This boxforms one section of the leveler ram and the other section is intelescoping relation to the first section and as shown comprises a pipe46 supported at the rear end by a truck formed of short axles 4E7carrying wheels or rollers 18 arranged to travel in the first section $5of the ram structure, as shown in Fig. 2. At the outer end of the secondsection of the ram there is a head 49 which may be variously shaped inaccordance with the desires of the designer. In the particular structureshown in the drawings there is a cross angle member 50 fast to the pipe46 a short distance from the outer end thereof and extending from nearthe ends of the cross member 50 to the outer end ofthe pipe is anotherangle member 51 of general taper form while the ends of the cross member50 are protected by shoes 52 which will engage the side walls of theoven and so guide the head 19 when-in the oven.

At the rear of the ram member 45 there are brackets 53 or other suitablefastening devices as shown in Fig. 6. Made fast to the drum 11 are theends of two strands 5 1-, preferably steel ropes, and these ropes arewound an appropriate number of times around the drum and are thencarried about direction changing idler rollers 55 and are continued fromthence to the brackets 53 to which the ends of the ropes 5% are madefast. Secured each at one end to respective ones of the brackets 53 areother ropes 51' car ried about direction changing idler rollers 57 tothe drum 11 about which the ropes 54: are wound an appropriate number oftimes alongside the ropes 5 1 in non-interfering relation thereto, andthe ends of the ropes are secured to the drum, it being customary to 1provide the drum 41 with grooves for the purpose after the usualpractice. The ropes 5% are wound on the drum in the opposite directionto the ropes 54 so that one set of ropes unwinds as the other winds uponthe drum.

The ram member 4C6 at the rear end car ries a fastening device 58 towhich are fastened the like ends of two strands 59, '60

is wound about the other drum 42. See

Fig. 7 There is also provided another strand 61 in the form of a steelrope, one end being made fast toa fixed portion of the structure, saythe rear end of the frame F. This rope 61 extends about a directionchanging idler roller 62 at the front of the ram section 15, thence tothe rear end of the ram section 4.6 where it passes about a directionchanging idler roller 63 carried by said ram section 16 thence aboutanother idler roller 64- corresponding to the roller 62 and finally backagain through the rear end of the ram section 45 to a fixed point of theframe F.

Let it be assumed that the ram is in the retracted or telescopedposition, then if power he applied to the drum l1 to rotate it in theproper direction the ropes 5st will cause a movement of the ram section45 outward from the casing F in which it is normally housed. Because ofthe fixture of the rear ends of the rope 61 to the casing or frame Fthese ends of the rope 61 do not participate in the movement of the rambut the rope 61 reacts on the roller 63 to carry the ram section asoutward with the ram section 15, but because the rope 61 passes aboutthe rollers 62 and 6 1 the ram section t6 will have imparted thereto aspeed double that of the ram section 45. have been projected to thegreatest extent, then the drum 11 may be'reversed and the strands 54passing around the rollers 55 will then act to draw the ram section 45into the frame 27; I

During the first operation, that of projecting the leveler ram, the druml2 simply turned idly permitting the paying out of the ropes 59 and 60.Now however power is applied to these drums l-2 to wind the ropes 59 andthereon, thus aiding in withdrawing the ram section 46 to telescopingrelation to the ram section 45, this being advisable because of theresistance offered to the rear end of the leveler head 49 by thematerial being acted upon.

The mechanism above described and shown in diagram in Fig. 7 serves totake up the slack in the cable 61 and to telescope the ram section 16into the ram section 15.

When the ram is first introduced into the coke oven the fuel charge isin the form of a heap highest at the center and the head 49 engages suchmaterial and forces it toward the other end of the oven and then on thereturn movement the rear edge of the head 49 also engages the materialand draws'it toward the first end of the oven. This operation may becontinued as long as necessary to level all the material in the ovenWhen the parts when the ram may ultimately be withdrawn from the oven sothat the section 45 is telescoped Within the casing or frame F and thesection 46 is telescoped Within the section 45. Any change in elevationnecessary for the frame or casing F to bring the leveling head 49 intoproper relation to the material to be leveled may be accomplished by aproper adjustment of the screw rods 16 in the manner already described.Because of the independent operation of either set of rodsl6 the levelerram may be caused to move in an inclined path rising or falling asdesired with reference to the floor of the oven. The telescopingleveling head actuating devices greatly reduce the extent of theleveling machine from the breast of the oven bank. It Will be observedthat since the relative movements of the ram sections 45 and 46 are asone to two, the drums 41 and 42 have the same relation as to their size.
